Alright! Now I'm getting some good info! I had also heard about the Rhino swap, but was told the Raptor cdi there as well. After you break it down that way it does make sense that the Raptor box probably wont help much. I am running Mud Lites, but i stuck with stock size tires and only have 25's all the way around. I havent noticed any power loss due to the tires. My thing is, and this may sound a bit ridiculous, I wanna be able to nail wheelies! I can now, if I stand on the back rack, but that is a pain and kinda dangerous. I dont wanna spend a grand just to ride wheelies though. Maybe Ill just be a rack wheelie rider!

the cams only cost $129 bucks...

 

hey don't know if this helps but i have tried to put an big gun cdi for a 450 rhino and it would not even start my 660 rhino put one in from a raptor and it would idle but would not move cut out back fired bad looking for a 660 grizzly cdi box and maybe it will work for my 660 rhino so i don't think that the raptor cdi box will work in your grizzly
